indeed.
i also did that a while ago when i wrote a custom interpreter and totally
forgot about it.

for such cases a C API lua_main() function resembling the "Tcl_Main()"
Tcl C API procedure could be added. a simple interpreter could
then be implemented using this function (if said function does not use
readline, else even the standard interpreter could use it).
